Abstract
Based on the theory of digital matched filter and advance-lag loop, a circuit of capture and tracking of PN-code with FPGA is realized using VHDL programming. The design of all module of the circuit is discussed in detail, the circuit simulation and validation is completed, and the simulative waveform is showed. Result shows that the circuit works normal and reliable, and the system extension is convenient and flexible, which can meet the design requirements well.关键词
